Question

A drop tower is a type of amusement ride incorporating a central structure of tower. Drop towers vary in height, passenger capacity, lift type, and brake type. Riders experience a free-fall initially, followed by rapid heavy deceleration. In terms of Oersted, Faraday, and Lenz’s law, which one can well explain the brake mechanism of the drop tower. How does it work?

Answer 1

Lenz's law explains it very much .

With most drop towers a gondola carrying riders is lifted to the top of a large vertical structure, then released to free-fall down the tower. These towers use  a magnetic braking system to slow the carriage quickly and smoothly once it reaches the bottom of the tower.

Each cart in the ride has permanent magnets under its seat. ... And as Lenz's law states, that magnetic field opposes the motion of the magnets. As a result, the magnetic field pushes up against the seat, causing the cart to slow down. This is how a drop tower's  magnetic brakes work.
